Write once type recording medium, recording device and recording method for write once type recording medium, and reproduction device and reproduction method for write once type recording medium

Abstract

On the write-once recording medium (10), there are provided: a certain defect management area (13) for definitely recording defect management information therein; and a plurality of temporary defect management areas (14A, 14B, and 14C ) to temporarily record defect management information in it. If the recording medium (10) is not finished yet, whenever the defect management information is updated, the updated defect management information is recorded in any one of the plurality of temporary defect management areas. In addition, a state information recording area (15) is recorded on the recording medium (10), and state information for representing the following temporary defect management area is recorded in the state information recording area (15). The defect management information recorded last is recorded. By referring to the status information, the defect management information recorded at the end can be quickly specified.

Description

technical field [0001] The present invention relates to a write-once recording medium, a recording device and a recording method for recording recording data on the write-once recording medium, and a method for recording recording data recorded on the write-once recording medium. A playback device and playback method for playback. Background technique [0002] As a technique that can improve the reliability of recording and reading recording data on high-density recording media such as optical disks, magnetic disks, and magneto-optical disks, there is defect management. That is, when there is a scratch or dust or wear on the recording medium (which is collectively referred to as a "defect"), the data to be recorded or recorded at the defective position is recorded in another area of ​​the recording medium (which is collectively referred to as "defect"). referred to as the "spare area"). As described above, by evacuating the recorded data that may be incomplete or imperfect...
